gonna be a tough job, watercooled that PC to the teeth, and currently don't have a second card, servers onboard but I can ask my flatmate for a 4670 I am sure, but not tonight, for tonight, we dine in hell! Or, at my Mums, so wont see him tonight

my asus 4870 dark knight died, it didnt even post or go to welcome on xp. just black black screen when i boot it up, but if i pull the power connectors off and then boot, it will display i dont have power connectors connected =/

hm... well, I went rather gung-ho and just bought another cheapo 4870 from PC World of all palces for £80. By my logic, it can still number crunch, so the new card can do the display nonsense, and I can just run Crossfire... surely that'll work! Failing that, RMA the 4870, sure Powercolor offered a 2 year warranty. Typically Ebuyers warranty ran out in October, so they won't touch it

threw a second 4870 in the second pcie, and nothing displayed, with the primary 4870 lifted out the second card worked fine in the second pcie slot, so gpu issues or mobo. Gonna put another card in the primary to check the pcie late still works, getting there I think
